    Hi Jeff,

    There aren’t many great studies looking at clinical end points, although this case control study by Battistella, et al. would suggest that users of both are at double the risk of UGIB in an elderly population.

    Arch Intern Med. 2005 Jan 24;165(2):189-92.
    Risk of upper gastrointestinal hemorrhage in warfarin users treated with nonselective NSAIDs or COX-2 inhibitors.
    Battistella M, et al.

    This Korean study by Choi, et al., shows an INR increase >15% in near forty percent of the patients in a review of 98 patients on coumadin in an outpatient clinic:

    J Korean Med Sci. Mar 2010; 25(3): 337–341.
    Risk Factors of Drug Interaction between Warfarin and Nonsteroidal Anti-Inflammatory Drugs in Practical Setting
    Kyung Hee Choi, et al.

    To me, these would suggest approaching that combination with caution, especially in the elderly or those with any risk factors for or history of bleeding, particularly GI bleeding.
